It's not about power, it's about the fact that Nero probably has more demon in him than Dante, a probability supported by the Devil Bringer. In other words, the psychological aspect of a demon are probably strong in Nero, which would at the very least make for an interesting internal struggle. Also, Nero himself said that he doesn't care if he becomes a demon as long as Kyrie is kept safe, so he's more likely to make rash decisions with potentially irreversible backlash, especially if Kyrie is in danger.
